I've been entering the same address, for years and they ended up changing my trailer to an apartment and now someone else has my order. TOTALLY NOT COOL. I contacted them on the contact page, and they were like "Just talk to the post offices front desk." Totally no help at all. And they are the ones who messed up my address.
Its okay, I ended up calling USPS. And they were a BIG help, Hopefully I get my package.
